We’ve all heard of hydroponics and the amazing medical marijuana that can be grown with it. However, choosing which hydroponic medium and method to utilize is something of a gray area. Your hydroponic setup can be as complicated or as simple as you like—it’s up to you. You can incorporate pumps, aerators, valves and switches, or you can fill a bucket with nutrient and simply pour the stuff on. The flexibility of hydroponics is one of the main reasons it’s so effective and popular.
For the second article in this series, we'll discuss probably the most popular method for growing hydroponic medical marijuana—Aerated Solution.
So you want to use the Ebb & Flood method because of all of its perks, but you’re not home during the day, and you’re no good with electrical things. Well, here’s your solution. Use the same growing tray and medium as you would with Ebb & Flood, but don’t use a reservoir. The reservoir is replaced with an aquarium aerator. Hoses from the aerator are snaked along the bottom of the growing tray, and then the tray is filled with your growing medium.
The idea is to have the growing tray constantly filled with the nutrient solution (and growing medium). The aerator blows air through the perforated hoses on the bottom, keeping the nutrient solution from becoming stagnant. This process is known as aeration, and is what keeps the fish alive in your aquarium. The rise of the air bubbles circulates the nutrient solution to provide fresh nutrients to the roots in a constant fashion.
With a setup like this, you need only to check for critters now and then, and replace the nutrient solution once or twice a week. It is the best solution for the working grower, providing absolutely amazing results with a minimum of complication. I’ve used this setup since figuring it out nine years ago, and have absolutely no complaints. The pleasant hum of that aerator puts me to sleep at night.
